Hi There, I am planning for 12 days trips where i will touch down @ KIX.
Hope to get some advice here.
We are parents bringing 4 child age from 5 to 12, so there will be a total of 6 PAX.
At the moment i haven't finalize my itenerary and am thinking to spend 3-4 days in Tokyo.
I am comparing the Transportation cost from Kyoto --> Tokyo and Tokyo --> Kyoto
Is anyone know the fare for 1-way and/or return ticket for Shinkansen? i bet it'd be quite expensive but i'd like my kids to try it.
Alternatively i m considering to rent a car(MPV). I briefly check online and get the following but i not sure correct or not

:
Pick up in the morning from Kyoto and Drop the car in the evening in Tokyo : Rental : +/-RM440.00
Using Tomei or Meishin Expressways estimate 600KM, so petrol +/-60litre x RM5 : +/-RM300
Toll fare : +/-RM400.00
TOTAL cost : +/- RM1,140.00 (excluding apply international license)
Please help to check whether it is correct and also the fare for shinkanses. I not familiar with Japan as this is my 1st trip. TQVM

For car rental, pick up at kyoto drop at Tokyo need to pay a drop off fees, for such a distance, it will cost you 24k yen
Focus on 1 area for you cases, since you have 6 persons, transportation in Japan is expensive
